Preferably, the guide rail set along electro spindle moving direction is provided with base, is provided with the lower surface of case
The sliding block coordinated with guide rail.
Compared with prior art, the utility model has the advantages that:
1) electric chief axis system is introduced the water into inside electro spindle by external catheter, it is not necessary to opened up on electro spindle into
Water hole, only need to cover after electro spindle to be threaded in production, convenient production, reduce production cost;
2) conduit of water flowing out structure covers after being connected to by connector, needs only to dismantle hollow spiral shell when dismantling conduit
Nail, the damaged possibility of screw thread covered after reducing;
3) case is additionally provided with the outer ring of water flowing out structure and supports guide rail and the sliding block combination of case, swivel joint branch
Support efficiently reduces water flowing out structure rocking when mobile and during water inlet, extends the life-span of water flowing out structure on case,
Precision during spindle processing is also improved simultaneously.

Embodiment
Describe to be used to disclose the utility model so that those skilled in the art can realize the utility model below.Retouch below
Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
A kind of electric chief axis system with water flowing out structure shown in Fig. 1-3, including base 1, the support that is fixed on base 1
Seat 2, the electro spindle 3 that is movably supported on support base 2 and it is supported on base 1 and is connected with the hollow space of electro spindle
Water flowing out structure.
The electro spindle 3 includes the bonnet 31 for being arranged on its end, and the hollow bulb with electro spindle 3 is provided with bonnet 31
Divide the through hole 32 of connection.The circulation of the operation principle and internal water of the electro spindle 3 uses prior art, no longer detailed herein
State.
The water flowing out structure includes the conduit 6 that water pipe head 7, one end are threadedly coupled with water pipe head 7, conduit 6 it is another
End communicates with the through hole 32 of bonnet 31.Water pipe head 7 with the external world water supply installation be connected, water by water pipe head 7, conduit 6 simultaneously
The hollow structure of electro spindle 3 is entered from the through hole of bonnet 31, finally flows out and then realizes to cutter from one end with cutter
Cooling.
In order to facilitate the connection of conduit 6 and bonnet 31, hollow connector is threaded with the through hole 32 of bonnet 31
5, the hollow space of the connector 5 is provided with internal thread, and one end of connector 5 is provided with hollow step in conduit 6, led
Aperture on pipe 6 at hollow step is less than diameter of the conduit 6 at connector 5, can thus be inserted by hollow screw 9
To conduit 6 and with the screw-internal thread fit on connector 5, and the screw head of hollow screw 9 is resisted against on the hollow step in conduit 6
To realize the connection of conduit 6 and the hollow space of electro spindle 3.Conduit 6 is connected to avoid with electro spindle 3 by connector 5 and led
Pipe 6 is directly connected to electro spindle 3, if be directly connected to, because conduit 6 needs often to dismantle, if the internal thread of bonnet 31 goes out
Now infringement must change whole bonnet 31, and use connector 5, when needing to dismantle conduit 6, it is only necessary to which hollow screw 9 is torn open
Unload, and by the cooperation of hollow screw 9 and connector 5 can share that the internal thread of bonnet 31 bears due to conduit 6
Active force caused by vibration, reduce bonnet 31 internal thread infringement possibility it is small, improve the service life of bonnet 31.Together
When, sealing ring is also equipped between connector 5 and bonnet 31 and is revealed to prevent stopping leak.
Sealing ring (not shown) is provided with the end face coordinated with connector 5 of conduit 6 to prevent stopping leak to reveal.It is also, logical
The reliability of seal ring seal can be adjusted by overregulating hollow screw 9, particularly after sealing ring uses a period of time, due to quilt
Extruding is without resilient so that sealing property is deteriorated, and this is can be realized further by further tightening hollow screw 9
Compress, improve the service life of sealing ring.
In order to be protected to water flowing out structure, the case 4 of both ends open, case 4 are additionally provided with the outside of water flowing out structure
One end be fixed on bonnet 31, the other end is provided with dismountable cover plate 41, and the water pipe head 7 passes through from cover plate 41,
Supporting plate 8 is provided with cover plate 41, the water pipe head 7 is supported in supporting plate 8 and fixed by screw that can reduce
Water pipe head 7 is rocked.
Sealing plate 42 is provided with the case 4, the conduit 6 passes through sealing plate 42, conduit 6 and sealing plate 42 it
Between be provided with sealing ring 43 to prevent the water in the external world from entering between sealing plate 42 and bonnet 31 that (space therebetween is set
It is equipped with some electronic components) to be caused damage to electronic component.
In order to further reduce water flowing out structure rocking when moving back and forth with electro spindle 3, it is provided with base 1 along electricity
The guide rail 11 of the moving direction extension of main shaft 3, the sliding block 12 coordinated with guide rail 11 is provided with the lower surface of case 4, by leading
The rocking when cooperation of rail 11 and sliding block 12 can ensure stability when case 4 moves and then reduce water flowing out structure movement.
